As the pilot began to lift the helicopter into a hover and to maneuver toward the lake to begin a departure, he felt the controls become stiff and observed that the “HYD” caption was again illuminated; the warning horn did not sound, however. The pilot maneuvered the helicopter to the departure site and conducted a landing; during the process, the helicopter’s tail struck branches, and the tail rotor was damaged.
The accident report said that the hydraulic sys-tem apparently had become disconnected from the flight controls before takeoff.
Helicopter Strikes Ground During Antarctic Flight

T
he helicopter was being flown in an attempt to circumnavigate the earth. On the morning of the accident, the crew had received a weather briefing in antarctica, about 600 nautical miles (1,111 kilometers) north of the South Pole, from a professional pilot who had years of experience flying in the Antarctic.
At departure, skies were clear, and the crew flew
the helicopter at 1,000 feet above ground level (agl) for about 240 nautical miles (444 kilome-ters), when cloud cover increased. Visibility was
good until the helicopter suddenly entered whi-teout conditions. The crew tried unsuccessfully to reverse course and then decided to attempt a landing.
“as the helicopter passed through about 200
feet AGL, the crew were still unable to see the surface, and the commander began to slow the

Flight Safety Foundation

Now you have
the safety tools

Approach-and-landing Accident Reduction

to make a difference.
Tool Kit

The Flight Safety Foundation is a comprehensive and practical resource on


compact disc to help you prevent the leading causes of fatalities in commercial aviation:
approach-and-landing accidents (ALAs), including those involving controlled flight into terrain (CFIT).
Put the FSF to work for you TODAY!



Separate lifesaving facts from fiction among the data that confirm ALAs and CFIT are the leading killers in aviation. Use FSF data-driven studies to reveal eye-opening facts that are the nuts and bolts of the FSF ALAR Tool Kit.


Volunteer specialists on FSF task forces from the international aviation industry studied the facts and developed data-based conclusions and
recommendations to help pilots, air traffic controllers and others prevent ALAs and CFIT. You can apply the results of this work — NOW!



Review an industrywide consensus of best practices included in 34 FSF ALAR Briefing Notes. They provide practical information that every pilot should know … but the FSF data confirm that many pilots didn’t know — or ignored — this information. Use these benchmarks to build new standard operating procedures and to improve current ones.
